Simplify : `3"x"-[4"x"-overline(3"x"-5"y")-3 {2"x"-(3"x"-overline(2"x"-3"y"))}]`
उत्तर
`3"x"-[4"x"-overline(3"x"-5"y")-3 {2"x"-(3"x"-overline(2"x"-3"y"))}]`
= 3x − [4x − 3x + 5 − 3 {2x − (3x − 2x + 3y)}]
= 3x − [4x − 3x + 5y − 3 {2x − (x + 3y)}]
= 3x − [4x − 3x + 5y − 3 {2x − x − 3y}]
= 3x − [x + 5y − 6x + 3x + 9y]
= 3x − [−2x + 14y]
= 3x + 2x − 14y
= 5x − 14y
